DECEMBER 26, 1918 l/.V.G. Constructional Details.—14. C.V. inter-plane strut ; 15. C.VI. inter-plane strut socket ; 16. Attachmentof strut to spar ; 17. Attachment of centre section strut to spar on C.VI. ; 18. Centre section struts and bulk- : heads of C.VI. ; 19. Bracing tube between rear chassis strut and engine bearer on C.V. and undercarriage. The angle between the rear two limbsof the N is practically bisected by the line of the fifth bulk- fiead, which finishes at the rear joint of fuselage and under-carriage. This is shown by a diagram, Fig. 18. The C.V. anachine has a sloping steel tubular strut between engineiiearer and rear undercarriage attachment (see Fig. 19), Ibut by the rearrangement of bulkheads the necessity for this2ias vanished, and the strut is not found in the later model. Fuselage'". The earlier types of L.V.G. had bodies built on the cross- t»raced girder system. Both the machines described possess-the same type of fuselage, totally different from the girder system, viz., a framework of bulkheads and longerons, covered-with a thin layer of 3-ply and totally without wire bracing. Fig. 20 gives the number of shapes of the bulkhead in the4i.V. machine, and incidentally reveals the shape of the fuselage. The C.VI. type has generally the same arrange-ment, but the third and fifth, bulkhead are no longer vertical in this model, and the tail part of the body has beenstrengthened by the insertion of another cross piece. -Although the fuselage of the L.V.G. biplane ends in avertical wedge, the provision of a centre section for the tail plane gives a cruciform appearance to this part. This isshown clearly by Fig. 21, where the two sides of the tail plane centre section are drawn in thin lines. The 3-plycovering to the fuselage rounds off the joint of body and tail plane in the neat way that is found in so many Germanaeroplanes. (See Fig. 22.) . Tail The shape of the fixed tail planes is shown in the G.A. drawings. The main box spar (see dotted section in Fig. 21) passes right through the body. The rear spar, to which t.V.G. Constructional Details.—20. The bulkheads of the C.V. fuselage; 21. Mounting of the tail plane ; 22. Stern of fuselage, showing plywood covering and mounting of tail skids ; 23. Protection piece for balanced portion of elevator ; 24. Tail skids of the two types. 1458
